Abstract

A prosthetic talus comprising: a base having a top surface and a bottom surface; and an articulating component having a top surface and a bottom surface, wherein the bottom surface of the articulating component is removably coupled to the top surface of the base, wherein the bottom surface of the articulating component includes a protrusion, and wherein the top surface of the base includes a recess configured to receive the protrusion to thereby removably couple the articulating component to the base, wherein the articulating component includes a sidewall positioned between the top surface and the bottom surface, and wherein the sidewall includes a plurality of holes.
